Diagnosis
The first step is to determine the cause of the ignition system problem. If the ignition system is not functioning correctly, there may be difficulty starting the car, decreased fuel economy, or the engine might misfire.
- Check for any codes on a code reader or scan tool (the tool must be OBD1 compatible as 1966 Ford Mustang doesn't support OBD2).
- Perform a spark test to check for any spark from the ignition.
- Inspect the distributor cap and rotor for any signs of arcing or carbon tracking.
Tools Needed
You'll need the following tools to successfully repair the ignition system:
- OBD1 compatible code reader
- Distributor wrench

Repair Steps
- Before starting, disconnect the battery's negative terminal.
- Remove the distributor cap but do not disconnect the plug wires. Inspect it for cracks, carbon tracks, or a worn rotor button.
- Remove the old ignition module and inspect it for burned spots or any damages.
- Install the new ignition module by applying dielectric grease on the bottom of the ignition module. Secure it with the bolts.
- Connect the wires back to the ignition module. They should click into place.
